Very high on our list of New Year’s resolutions is “Get our asses to a Metalachi show.” L.A.’s preeminent metal/mariachi mashup band has by all accounts been killing it of late, and they just achieved another career milestone last week when they performed a Slayer cover with an actual member of Slayer: drummer Dave Lombardo, who lent his mighty kick rolls to a south-of-the-border rendition of “Raining Blood” at the Roxy on Sunset last Friday.

Behold the Metalachi mayhem in the clip below. The sound quality ain’t great, and neither is the camera work (especially when the cameraman starts headbanging about midway through—but can you blame him?). But you get the idea.

I’m the cameraman lol. I know the sound quality isn’t perfect, but then again the bass in person was loud to where I felt like i was being punched and my camera caught that. I have other videos from other concerts where the sound is crystal clear. Yes I did headbang but had I known my video would’ve gone to a few metal sites, I would’ve definitely contained myself from headbanging.
